Hoppe's No. 9 Gun Bore Cleaning Solvent 1-Quart Bottle — Concentrated, Rust-Removing Formula

Hoppe's No. 9 is a time-tested gun bore solvent in a 1-quart bottle that quickly loosens and removes powder residue, lead and metal fouling, and surface rust.

First mixed in 1903, Hoppe's No. 9 has been refined into a concentrated cleaner favored by shooters, hunters, gunsmiths, and collectors who need a reliable solvent that penetrates fouling and simplifies bore maintenance. This one-quart formulation delivers the original ultra-potent formula in a user-friendly bottle with a child-proof cap and is designed for use on a wide range of firearms and calibers.

How does Hoppe's No. 9 remove fouling and rust?

The solvent is formulated to break down powder residues, lead deposits, metal fouling, and light rust by penetrating and dissolving built-up contaminants. It works quickly on contact so you can reduce scrubbing time and restore bore surfaces more efficiently.

• Deep-penetrating solvent action loosens embedded fouling
• Targets lead, powder, copper, and light surface rust
• Reduces the need for excessive mechanical brushing
• Concentrated formula treats multiple cleaning sessions per bottle

Is Hoppe's No. 9 safe and easy to use?

Hoppe's No. 9 is designed to be straightforward for routine firearm maintenance: apply with a patch, brush, or cloth, allow time to work, then remove residue and dry the bore.

• Apply with standard cleaning rod, patch, or bore brush
• Works on revolvers, rifles, shotguns, and muzzleloaders
